Approvals
The Fireray ® 3000 Exd complies with the ATEX directive.
II 2GD IP66: Ex d IIC T5 Gb / Ex tb IIIC T95°C Db
Operation
The Transmitter head emits a narrow beam of infrared light to an associated Receiver head. Once smoke crosses through and thus obscures the IR beam path, the signal strength at the Receiver drops below a preset level which in turn results in an alarm condition.
The Fireray ® 3000 Exd has been designed so that it can be installed by one operator, with its laser-assisted alignment method combined with easy-to-use alignment LEDs offering visual feedback. An integrated laser alignment aid can be activated at the Controller.
The Fireray ® 3000 Exd also has a feature that allows for the Transmitter to be powered from the Controller by wiring directly, thus reducing the number of power supplies required.
The low-level Controller incorporates an LCD display, which offers a full icon-based, easy-to-use interface unit. This Controller enables ease of commissioning, testing, and maintenance of the beam detection system. During commissioning the detector’s fire sensitivity thresholds can be selected, along with the user variable time to fire and time to fault settings.
The system is fully compliant with the requirements of RoHS and WEEE.
